JEDDAH — Jeddah Police arrested a gang of six Yemenis who allegedly robbed petrol stations disguised as policemen. They stole SR35,000 and sped away in their car. Investigators from a south Jeddah police station started monitoring petrol stations that were the robbers' possible target. After several days, an undercover police unit noticed a vehicle driving suspiciously and arrested the occupants when they got out at a gas station. Jeddah police spokesman First Lt. Nawaf Al-Bouq said the suspects were aged between 22 and 36.
